摘要： PROBLEM TO BE SOLVED: To provide a cooling device and a cooling method of an attachment capable of efficiently cooling the attachment in a machine tool. SOLUTION: This cooling device 1 is mounted on the attachment 100 attached to a main body spindle of the machine tool. The cooling device 1 comprises heat conducting parts 40 and 50 for conducting the heat produced in the rotation of a spindle 130, to the cooling liquid, a heat exchanger for allowing the cooling liquid to radiate to be cool, and a circulation pump 30 for circulating the cooling liquid among the heat conducting parts 40 and 50 and the heat exchanger 20. Accordingly, the circumference of the spindle 130 of the attachment 100 can be surely cooled. Further by using the attachment 100 capable of increasing a speed of rotation of a working tool, holes of a small diameter can be formed at high rotation in a large machine tool, and the productivity can be remarkably improved.

摘要： PROBLEM TO BE SOLVED: To decrease the stroke of a milling cutter in the case of milling the end face of a shaft product such as a crankshaft and forming a center hole.
SOLUTION: A center drill 42 is disposed in the center of a ring-like milling cutter 40. First the milling cutter 40 is caused to approach the shaft product 30 so that the end face 31A of the shaft product 30 is directed to the inside of the milling cutter 40. Subsequently, while the milling cutter 40 is moved so that the end face 31A of the shaft product 30 moves from the inside of the milling cutter to the outside, the end face 31A of the shaft product 30 is subjected to milling by the milling cutter 40. After that, the end face 31A of the shaft product 30 is returned to the inside of the milling cutter 40, and the center hole is formed by the center drill 42.

摘要： PROBLEM TO BE SOLVED: To provide a grinding machine capable of easily and exactly detecting a change of a relative angle of a workpiece and a grinding wheel.
SOLUTION: This grinding machine is provided with a workpiece base 5 for supporting the workpiece 8, a grinding wheel base 13 for supporting the grinding wheel 16, while rotating and driving the grinding wheel 16, and a movable mechanism capable of adjusting an angle of the grinding wheel base 13 on a supporting base 12. Inclination of the grinding wheel 16 is detected by a difference of displacement of a first sensor 53 and a second sensor 54. At this time, a distance between the two sensors 53 and 54 is constituted to be wider than a grinding width of the workpiece 8. As a result, only the inclination is extracted, apparent sensitivity of the sensors 53 and 54 is enhanced, and the change of the relative angle of the workpiece 8 and the grinding wheel 16 can be exactly detected.
